Boat Operation

Trailering

If Boston Whaler supplied the trailer for your boat, it is

designed specifically for your boat and it is commer-

cial-grade. The trailer construction is heavy-duty and

it exceeds the capacity requirements for your boat.

This trailer might be equipped with additional

upgrades to suit your mission.

Regulations controlling trailer equipment and manu-

facture vary from place to place. You must verify that

your trailer meets the laws and transportation regula-

tions in the states or countries where you use it.

Refer to the trailer owner’s manual for detailed infor-

mation about the operation and maintenance of this

trailer.

CAUTION

Do not trailer your boat with the engines in their

fully tilted position.

CAUTION

Center the engines before tilting to avoid

contact with any special towing equipment on

your boat.
